AbstractComplementary optical and neutron-based vibrational spectroscopy techniques (Infrared, Raman and inelastic neutron scattering) were applied to the study of human bones (femur and humerus) burned simultaneously under either aerobic or anaerobic conditions, in a wide range of temperatures (400 to 1000 °C). This is the first INS study of human skeletal remains heated in an oxygen-deprived atmosphere. Clear differences were observed between both types of samples, namely the absence of hydroxyapatite’s OH vibrational bands in bone burned anaerobically (in unsealed containers), coupled to the presence of cyanamide (NCNH2) and portlandite (Ca(OH)2) in these reductive conditions. These results are expected to allow a better understanding of the heat effect on bone´s constituents in distinct environmental settings, thus contributing for an accurate characterisation of both forensic and archaeological human skeletal remains found in distinct scenarios regarding oxygen availability.

We have critically investigated the ATR-IR spectroscopy data behavior of burned human teeth as opposed to the generally observed behavior in human bones that were subjected to heat treatment, whether deliberate or accidental. It is shown that the deterioration of the crystallinity index (CI) behavior sometimes observed in bones subjected to high temperature appears to be of higher frequency in the case of bioapatite from teeth. This occurs because the formation of the β-tricalcium phosphate (β-TCP) phase, otherwise known as whitlockite, clearly ascertained by the X-ray diffraction (XRD) patterns collected on the same powdered specimens investigated by ATR-IR. These results point to the need of combining more than one physicochemical technique even if apparently well suitable, in order to verify whether the assumed conditions assessed by spectroscopy are fully maintained in the specimens after temperature and/or mechanical processing.

We describe 17 medieval kurgans at Murlinka, dating to the late 1st millennium AD and associated with archaeological sites at Aitkulovo, in the Tarsky District of the Omsk Region, on the right bank of the Irtysh, in the borderland between the forest-steppe and the taiga. The deceased were buried in a supine extended position. Some burials were made on the virgin soil, and some on the buried soil. Most kurgans accommodated one grave, but in some cases the number of graves was two and more. Inside the kurgans, at the buried soil level and above, limb bones of animals and small potsherds were found. In certain graves, traces of fi re, such as partly burned bones, charcoal, ash, or charred earth, were detected. We also found ditches and various structures inside the mounds. In eleven mounds, there were funerary offerings, such as vessels, arrowheads, celts, bits, and ornaments, similar to those found in the graves. We give a detailed description of bronze ornaments and pommels, tools, and belt sets made of white metal, as well as glass and ceramic beads, iron artifacts, details of horse harness, iron and bone weapons, and pottery. Parallels are found in the taiga regions of the Middle Ob, Ural, and the steppe zone of northern Altai. We discuss the chronology and cultural attribution of the fi nds in the context of the ethnic processes that occurred in the region.

This paper deals with a unique glass bead from the second millennium BC in Wessex. Overlooked for more than 150 years, it has now been recognized for its intrinsic interest and general importance and is here presented for its wide significance in ancient Europe and beyond (pls 8 and 9).InAncient Wiltshire(1812, 210) Richard Colt Hoare recorded the excavation of a barrow in a group of Bronze Age date at Wilsford: ‘No. 7 is a large bell-shaped barrow’ (now regarded as a bowl barrow) ‘composed entirely of vegetable earth. It contained within a cist a little pile of burned bones with which had been deposited a very fine brass pin, a large stone bead which had been stained red, a bead of ivory and a lance head of brass’. This account is based on the records of William Cunnington (1807, 5–6), which include a transcription of a letter from the original excavator, a Mr Owen. The dimensions of the barrow are there given as 80 ft in diameter, 9 ft high, with a circular cist 18 in deep. The barrow is described as ‘No. 6 of Mr Duke's barrows’; there is thus a discrepancy in the numbering of the barrow, since Colt Hoare referred to it as Lake No. 7, while Cunnington kept to No. 6. The barrow, though recently ploughed, still stands to a height of over 2 m, and is today known as G.42 (Grinsell 1957, 211).
